To all whom it may concern: I j

Be it knownthat I, JOHN J. ZWALSH, a

citizen of the United States, residing at Cleveland, in the county of Cuyahoga. and

( State of Ohio, have invented new and useful Improvements in Auxiliary Vehicle Wheels, of which the following" is aspecificatiom This invention relates to attachments to the wheels of motor vehicles and the-like and has for its object the provision of a novel auxiliary wheel desi ed, to be clamped upon the outer side 0 an ordinary automobile wheel and acting to prevent sinking of the vehicle wheels into the mud or into snow. w

An important object is the provision of an auxiliary wheel of thistcharacter which is rovided with means whereby it may be -qu1ckly and easily clamped upon the spokes of the vehicle wheel, the auxiliary wheel further including a central collar member adapted to be embracingly engaged upon the hub portion of a vehicle. wheelr Yet another object is the provision of a novel form of clampingmeans for securing the auxiliary wheel in place.- D

A still further object is the prov1sion of an auxiliary wheel ofthis character which has its periphery provided with llbS or cleats which act to bite into soft or spongy ground and give the necessary tract-1on1 in addition to preventing slipping and skiding. f

An additional object is-the rovision of a deviceof this character whic will be simple and inexpensive to manufacture, easy to.

apply or install, positive in action, eflic ent and durable in service, and. a general unprovement in the art.

With the above and sother objects and advantages in view, the invention-consists in the details of construction to be hereinafter more fully described and claimed, and illustrated inthe accompanying drawings in which:

Figure 1 is a side elevation of the auxiliary wheel showin it applied to-a vehicle wheel, parts being. roken away Figure '2 is a section on the line 2-2 of Figure 1, the entire side disk being shown in a plied position and not broken away as 33 of Figu in igure 1 and- Figure 3 is a detail section on the line re 1. -R'eferring more particularly to the drawbrace members 19 whic v collar 14 by any desired means. and-riveted in s, the {letter A designates", broadly, a ve icle wheel of ordinar type including the usual hub B from whic radiates spokes C carrying a felly D on which is mounteda rim E carrying a pneumatic cushion=tireFZ*- In carrymg outmy' invention I provide an auxiliary wheel which comprises a cylindrical band or rim '10 havin an inturn'ed flange 11 at its outer edge to w ichis adapted to be secured, as for instance by means of screws or bolts 12, a disk 13 which forms a a closure for the outside of the auxiliary wheel. The numeral 14 represents a ring 7 like collar which is of suitable-size to'be engaged upon the hub portion B of the ve hicle wheel A. Suitably secured to and ra diating from this collar 14 are'spokermemhere 15 of compound curved shape which have their outer ends laterallyextended as shown at 16 and riveted or otherwise. so

cured against the inner periphery of the band 10. I also prefer to equip the periphery of the band with transverse IllJS I or cleats'17 which might be held in place by 7 any desired means but which are here-represented as secured by the rivets-18 employed for holding the spoke members to the band. Of course any desired number vof thesev spokes may be provided though'in' the present instance I ave re resented onlyfouras this is a reallysu cientnumber. Located between the s okes 15 are radial h are secured to-the or otherwise fastened to the inner periphery of the band, 10 drawings.

In order to attach this auxi'liary-wheelto I the vehicle wheel A, I make use of a plurality. of clamp-devices designated broadly by the numeral 21, which clamp devices are as clearly shown. in the associated with and carried by the-spokes 15. v

Each clamp comprises a U-shaped bolt member 22 having one .leg 23." longer thanthe other and threaded so as to carry an adjust-- lug nut 24. The other leg of t e -U-bolt is coiled or formed into an eye 25 pivotally enthe ve icle wheel A, subsequently to which the clamping plate 27 is intended to be swung into engagement with the vehicle wheel spokes'f in which position-it wiil be firmly. held by screwing down. the nut 24. To avoid damaging the vehicle wheel spoke it is; prefe able that the clamping plate- 27 be. provided with a lining 29 of felt, rubber or other soft material.

jIl l-QOIdGP-lZO app] .the auxiliary wheel, it is necessary that-t e' disk 13 forming the closure therefor be removed in order that access ma be had to the clamping devices 21. The evice is placed'against the vehicle wheel A, the nut' 24 bein s aced away from the bight'portion of t e -bolts, and the U-bolts are then hooked about the vehicle wheel spokes a, subsequently to which the clamping plates 27 are swung into osition and the nuts 24 turned down to e ect the holding action. After this securing is acessary complished, the closure disk 13 is applied and held by the bolts 12.

In the use of the device it will be quite evident that the wide flat surface of the auxiliary wheel will ride upon the ground and prevent sinking of the vehicle wheel into the ground, the device being of great advanta e when travelling over soft, bo gy or mud y ground. It is of course true t at the device is of equal advantage when travelingover snow es ecially as the transverse ribs or cleats 17 Wlll operate to give the neotraction so that the wheels cannot spin idly.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply constructed, inexpensive. and easily apphed device for the purpose specified which .will efliciently perform all the functions for which itis intended and which on account ofthe fewness of parts and theruggedness of construction is not likely to get out of order but should have a long and satisfactory life.

While I have shown and described the preferred embodiment of the invention, it should be understood that I reserve the right to make such changes in the form,- construction and arrangement of parts as wi1l not depart from the spirit of the invention or the scope of the subjoined claims.

' member being Having thus described the invention, I claim:' I

1. Means for securing an auxiliary wheel upon a vehicle wheel of, the spoke type the auxiliary wheel having spokes, comprising plate members disposed against the spokes of, the auxiliary wheel and formed with slots at one end, U-shaped members pivotally connected at one end with said plate members and having their other ends formed with threaded extensions, said U-shaped embracingly engaged about the spokes o the vehicle wheel with the threaded extensions passing through the slots, and nuts on said extensions for effecting a clamping action.

2. An auxiliary wheel for attachment to the wheels of a motor vehicle, comprising a c lindrical band, a collar member located at t e center of the band, a plurality of spokes radiating from the collar and secured thereto and to the band, and clamping means carried by said s okes and adapted for engagement about tlie spokes of a vehicle wheel, said clamping means com rising a plurality of U-bolts arranged in em racing relation to said spokes and adapted to be engaged about the spokes of the vehicle wheel, and clamping means carried by said U-bolts.

3. An auxiliary wheel for attachment to the wheels of a motor vehicle,-comprising a cylindrical band, a collar member located at t e center of the band,a plurality of spokes radiating from the 'collar and secured thereto and to the band, and clamping means carried by said spokes and adapted for engagement aboutt e spokes of a'vehicle wheel, said means comprising a U-bolt straddling each of said first named s okes and having one arm longer than the ot er and threaded, the shorter arm being coiled to define an eye, a clampingplate pivoted at the eye and having a slotted end for engagement upon the longer leg of the U-bolt, and a nut engaged upon said threaded end for urgin said clamping plate into engagement with the vehicle wheel spoke.

In testimony whereof I aflix my signature.

JOHN J. ZWALSH.
